To all whom it may concern: I

Be it known that I, HARRY HEY, a subject of the King of Great Britaimresiding at Dewsbury, Yorkshire, England, have invented certain new and useful Improvements in Absorbers and Separators for Gases and Vapors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in absorbers and separators for vapors and gases of the type in which the vapors and gases are brought into contact with absorbent liquid which is caused to circulate through the apparatus in a direction contra to that in which the are circulated.

The object of the invention is to provide an absorber which shall be very eflicient-and which is-so arranged as to cause the gases and vapors and the absorbent liquid to come into very intimate contact.

The invention will be best explained with reference to the accompanying drawings in which Figure 1 is an elevation in partial section of an absorber in accordance with the present invention. Fig. 2 is also an elevation in partial section showing various modifications, while Fig. 3 is a detail view hereinafter explained.

According to the present invention the vapors and gases are passed in one direction' through the apparatus while the absorbent liquid is passed through the apparatus in the opposite direction. Both the vapors and gases and the absorbent liquid are caused to pass over and through corrugated plates which are so arranged that the depressions in one plate enter somewhat into the depressions in the plate immediately below so that a large number of small traps are made which hold the absorbent liquid through which the gases and vapors have to pass in their progress through the apparatus. By this means an absorber is formed which is more or less of the so-called bubble scrubber type in which owing to the arrangement of the corrugated plates the scrubbing effect on the gases and vapors is gases and vapors very greatly increased. Provision can also be made for rotating some of the plates relative to other of the plates to increase the scrubbing action while in addition those plates which are capable of rotation can be given a reciprocating motion in a direction at right angles to their planes so as to cause the pressures between adjacent plates to continually alter. This reciprocating motion also acts as a means for forcing the absorbent liquid down through the apparatus.

The application as herein described is prima'rilyintended for use for the absorption benzin used in dry cleaning, and the absorbent liquid in this case is oil. It is not to be understood,.however, that the application is to be limited to the use of 011 as the absorbent liquid, since it is obvious that the apparatus could be used for other purposes, such as the absorption of ammonia from air by means of water.

Referring now to Fig. 1 it will be seen that corrugated plates at with concentric corrugations are arranged with orifices b at the apices of the corrugations while immediately below each of the plates (1 there is arranged a correspondingly corrugated plate 0 with an orifice d at the bottom of the depresslons of the corrugations. These corrugated plates a and 0 are arranged in a suitable casing 6 being held in their rela-.

tive positions by spacing rings f. The ab sorbent liquid is forced into the apparatus by the pipe 5] which is perforated at h. The outlet for the absorbent liquid and the gases which it has absorbed is shown at j. k is an inlet for the gases and vapors and s is the outlet for the same.

In working the absorbent liquid passing in by the pipe 9 will pass through the holes 11- and fall into the depressions in the cor rugated plates 0 and will gradually overflow by the orifices b and fall down on to the plates 0, through the orifices d on to the next plate a and so on while the gases and vapors will pass up in a contra direction and will have to pass through the orifices b of the plates a and through the liquid in the depressions in these plates a and will pass up through the orifices d in the plates 0.

In the more complicated arrangement shown in Fig. 2 the lates at are secured to a central shaft Z and are so arranged as to leave a free space between their outer peripheries and the spacing rings 7 which support the other corrugated plates 0 which latter have a central aperture 0 so as to ,65 of the vapors of volatile llquids, such as absorbent liquid and has also an intermediate chamber to.

leave space bet-ween their inner peripheries and the shaft Z. The shaft Z passes through the top of the casing e where it has'secured to it a worm wheel at which is operated by a worm n rotated from a suitable pulley o. The casings is formed with a well 1) for the has an outlet g. The casing-e through by the 2 into t e well 12. This intermediatecham ber 'w is provided with'an inlet 1' for the gases and vapors which pass up through the orifice e and are;caused to pass from the inner periphery of the plates vc over the plates 0 andaufirler the plates at until they pass up around the outer periphery of the plates at and underthe plates 0 and so on up to the outlet 8. .The' absorbent liquid is fed into the apparatus by any suitable pipe The lower end of the shaft 5 is located in a socket't about which socket there is arranged a circular inclined piece or cam it while there is arranged a correspondingly shaped circular piece or cam '1; secured to the shaft Z. The shaft l issecured to the gear which the absorbent liquid" passes wheel 'm by a sliding keyway 2 so that on of the the shaft Z being rotated the sliding part 1; over the part a will impartv a reciprocating 'motion to the shaft in the direction of its length and-so cause the-corrugated 4 plates a to be raised and lowered relative to the corrugated plates: 2, decrease and increase in the pressures between these plates and causing-a very intimate admixture of the absorbent liquid and the gases and-at the sarne- .time forcing the absorbent liquid down over the plates As the increased ressure at times between the plates may raise the temperature somewhat any suitable pipe 5 may be arranged for-the circulation of cooling iliquids. An additional efi'ect is'produced bythe rotation of the shaft] in that it causes the rotation of the corrugated plates a relative to the corrugatedplates 0 so that the bubbies of the gases and-vapors which pass along the plates will tend'to be attenuated and broken up so that the gases and vapors will be brought "into still more intimate contact with the liquid; v The detail view shown in Fig. 3 indicates an arrangement whereby it is possible to cause the reciprocation of the shaft Z in the direction of its length without causing the same to rotate. According to this arrangement the gear wheel at is rotatably mountedon the shaft Z, and on the upper surface of the boss is rovided with the incline a while the shaft 'abovegkthis carries a correspondmg incline or cam '0 so that on the rotation of tli gear wheel m the incline or cam 14 w 1ll raise the-cam o and allow it to fall again 1n which movement'this, c'am {a will carry the shaft 1 which is prevented ipe a: or through the orifices y and.

causing a continual into ,the depressions of the Loa ers from rotating-by sliding keyway 3 whereby it is connected to the boss 4 on the head of i the casing.
